Abstract
Objectives: We evaluated the usefulness of intradermal smear microscopy (IDS) in the detection of asymptomatic malaria parasitaemia in pregnancy. Peripheral venous blood (PVB) served as control. The preference for the collection technique of dermal blood was also assessed.
Patients and methods: One hundred and fifty (150) asymptomatic women were recruited. They had both intradermal smear and peripheral venous blood smear were made for all patients. Measures of test validity included sensitivity, specificity and accuracy rate. Test of statistical significance was with Yates correlation at 95% confidence limit.
Results: The prevalence of asymptomatic malaria parasitaemia was higher using intradermal smear (35.3% vs 33.3%) though this was not statistically significant. Intradermal smear had a sensitivity of 40% and specificity of 67%. The positive predictive value was 37.8% with accuracy rate of 58%. 41% of participants preferred the technique of collection of intradermal blood.
Conclusion: Intradermal smear appears to have no usefulness in the detection of asymptomatic malaria parasitaemia in pregnancy. However, we recommend more studies on its value in pregnancy, especially amongst symptomatic pregnant women.
